Narcissism and related need satisfaction among German social network users

Positive correlations between online social networking and narcissistic behaviors and traits can be regarded as common sense among traitpsychological online research today. However, it still remains unclear what underlying factors motivate narcissistic individuals to engage in social interactions on websites such as Facebook. This study investigates trait narcissism (measured by the Narcissistic Personality Inventory) and narcissism-related needs on social networking sites. Therefore, perceived possibilities of satisfying three narcissism-related needs (1. need for attention and admiration, 2. need for self-disclosure and self-presentation, and 3. need for self-esteem) are investigated for face-to-face communication and communication on social networking sites measured by newly developed scales. The goal is to see whether or not narcissistic individuals seek out online social interactions because these needs can be better met on social networking sites than in face-toface communication. A questionnaire survey among German students (N = 886) revealed significant relations between trait narcissism and usage of social networking sites. Regressions analyses and t-tests show that narcissistic individuals use social networking sites more often and intensively, however, when it comes to satisfying typical narcissistic needs, face-to-face communication is rated as being more suitable to meet the needs for attention and admiration as well as self-disclosure and self-presentation. Results indicate that online social networking is not particularly rewarding for narcissistic individuals, yet another much appreciated means of narcissistic behavior.Positive Zusammenhänge zwischen Online Social Networking und narzisstischen Verhaltensaspekten wurden vielfach in der Forschungsliteratur berichtet. Es bleibt jedoch unklar, weshalb narzisstische Personen Social Networking Sites wie Facebook häufiger und intensiver nutzen. Die vorliegende Studie untersucht subklinischen Narzissmus (durch das Narcissistic Personality Inventory) sowie typische Bedürfnisse narzisstischer Personen auf Social Networking Sites. Mit Hilfe neu entwickelter Skalen wird getestet, ob die drei typisch narzisstischen Bedürfnisse (1. Need for Attention / Admiration, 2. Need for Self-Disclosure / Self-Presentation, 3. Need for Self-Esteem) offline in Face-to-Face-Kommunikation oder online auf Social Networking Sites besser befriedigt werden können. Hierdurch soll die Frage beantwortet werden, ob narzisstische Personen eine Präferenz für Online Social Networking entwickeln, da sie dort ihre typisch narzisstischen Bedürfnisse besser befriedigen können. Eine Fragebogenerhebung unter 886 deutschen Studenten bestätigt korrelative Zusammenhänge zwischen Narzissmus und der Nutzung von Social Networking Sites. Regressionsanalysen und t-Tests zeigen, dass narzisstische Personen Social Networking Sites häufiger und intensiver nutzen. Für die Befriedigung von typisch narzisstischen Bedürfnissen (1. Need for Attention / Admiration, 2. Need for Self-Disclosure / Self-Presentation) wird jedoch Face-to-Face-Kommunikation präferiert. Die Ergebnisse deuten darauf hin, dass Online Social Networking im Vergleich zu Face-to-Face-Kommunikation nicht sonderlich lohnend für narzisstische Personen ist, sondern lediglich eine zusätzliche Möglichkeit narzisstischer Selbstdarstellung und Bedürfnisbefriedigung darstellt

The Functional Ability of MCI and Alzheimer’s Patients Predicts Caregiver Burden

Research shows that caregivers of dementia patients experience burden and psychological distress, but it is unclear whether or not caregivers of individuals with cognitive impairments that do not meet a diagnosis for dementia also experience similar burdens and psychological problems. Sixty patients and their caregivers participated in this study designed to examine caregiver burden. The patients completed activities-of-daily-living tasks and several neuropsychological tests assessing memory, abstract reasoning, and language. Caregivers completed self-report measures assessing caregiver burden and psychological distress. Results revealed that the caregivers of patients with mild Alzheimer’s disease (mAD) reported greater physical burden and feelings of missing out on life compared to individuals with mild cognitive impairment (MCI) caregivers. The mAD caregivers indicated greater depression and anxiety relative to MCI caregivers. Stepwise regression found that patient neuropsychological scores were worse predictors of caregiver burden than patients’ daily functioning. The conclusions of this study suggest that (1) caregivers of mAD are likely to experience more severe types of burden and psychological distress relative to caregivers of MCI patients, and that (2) patients’ daily functional abilities better predict caregivers’ burden and psychological distress than patients’ neuropsychological functioning. Study findings suggest that caregivers of those in the early stages of dementia, even in persons not yet meeting a diagnosis, experience psychological symptoms and burden, and that these caregivers’ experiences can be best predicted by the patients daily functional ability than by patients’ neuropsychological test scores

Benchmarking of different approaches to forecast solar irradiance

Ponencia presentada en: 24th European Photovoltaic Solar Energy Conference and Exhibition celebrada del 21-25 de septiembre de 2009 en Hamburgo.Power generation from photovoltaic systems is highly variable due to its dependence on meteorological conditions. An efficient use of this fluctuating energy source requires reliable forecast information for management and operation strategies. Due to the strong increase of solar power generation the prediction of solar yields becomes more and more important. As a consequence, in the last years various research organisations and companies have developed different methods to forecast irradiance as a basis for respective power forecasts. For the end-users of these forecasts it is important that standardized methodology is used when presenting results on the accuracy of a prediction model in order to get a clear idea on the advantages of a specific approach. In this paper we introduce a benchmarking procedure to asses the accuracy of irradiance forecasts and compare different approaches of forecasting. The evaluation shows a strong dependence of the forecast accuracy on the climatic conditions. For Central European stations the relative rmse ranges from 40 % to 60 %, for Spanish stations relative rmse values are in the range of 20 % to 35 %

Dietary and Lifestyle Patterns in the Spanish Pediatric Population (One to <10 Years Old): Design, Protocol, and Methodology of the EsNuPI Study

The interest in a healthy diet and lifestyle during the early stages of life increased, pointing out its role in the development of noncommunicable chronic diseases throughout adult life. Dietary habits and dietary patterns begin to be established in early childhood and persist during adulthood. Therefore, the EsNuPI (“Nutritional Study in Spanish Pediatric Population”) study aims to depict the dietary patterns, physical activity, and sedentary behaviors in Spanish children aged from one to <10 years old. This prospective, cross-sectional, observational study recruited a total of 1514 children from Spanish cities with >50,000 inhabitants, stratified by Nielsen areas. Participants were involved in one face-to-face survey, followed by a telephone survey after at least one week. Information about dietary intake and habits was obtained using a quantitative food frequency questionnaire and two 24-h dietary recalls. Physical activity and sedentary behaviors were registered using a specific questionnaire based on a seven-day record. Data were processed and stratified by categorical variables to be statistically analyzed in order to meet the study objectives. This study is the first of its kind in a Spanish reference population of this age range and the first to evaluate whether the consumption of adapted milk formulas and dairy products is associated with healthier dietary patterns and better diet quality and lifestyles in this group.This research was funded by Instituto Puleva de Nutrición (IPN)

Safety and immediate humoral response of COVID-19 vaccines in chronic kidney disease patients:the SENCOVAC study

BACKGROUND: Chronic kidney disease (CKD) patients are at high-risk for severe Covid-19. The multicentric, observational and prospective SENCOVAC study aims to describe the humoral response and safety of SARS-CoV-2 vaccines in CKD patients. Safety and immediate humoral response results are reported here. METHODS: Four cohorts of patients were included: kidney transplant (KT) recipients, haemodialysis (HD), peritoneal dialysis (PD) and non-dialysis CKD patients from 50 Spanish centres. Adverse events after vaccine doses were recorded. At baseline and on day 28 after the last vaccine dose, anti-Spike antibodies were measured and compared between cohorts. Factors associated with development of anti-Spike antibodies were analyzed. RESULTS: 1746 participants were recruited: 1116 HD, 171 PD, 176 non-dialysis CKD patients and 283 KT recipients. Most patients (98%) received mRNA vaccines. At least one vaccine reaction developed after the first dose in 763 (53.5%) and after the second dose in 741 (54.5%) of patients. Anti-Spike antibodies were measured in the first 301 patients. At 28 days, 95% of patients had developed antibodies: 79% of KT, 98% of HD, 99% of PD and 100% of non-dialysis CKD patients (p<0.001). In a multivariate adjusted analysis, absence of an antibody response was independently associated to KT (OR 20.56, p = 0.001) and to BNT162b2 vaccine (OR 6.03, p = 0.023). CONCLUSION: The rate of anti-Spike antibody development after vaccination in KT patients was low but in other CKD patients it approached 100%; suggesting that KT patients require persistent isolation measures and booster doses of a Covid-19 vaccine. Potential differences between Covid-19 vaccines should be explored in prospective controlled studies

Epidemiological and clinical characteristics of Streptococcus tigurinus endocarditis

Background: Streptococcus tigurinus was recently described as a new streptococcal species within the viridans group streptococci (VGS). The objectives of the present work were to analyse the clinical and microbiological characteristics of S. tigurinus isolated from patients with bacteraemias, to determine the prevalence of S. tigurinus among VGS endocarditis in Spain, and to compare the clinical characteristics and outcomes of endocarditis caused by S. tigurinus and other VGS. Methods: Retrospective nationwide study, performed between 2008 and 2016 in 9 Spanish hospitals from 7 different provinces comprising 237 cases of infective endocarditis. Streptococcal isolates were identified by sequencing fragments of their 16S rRNA, sodA and groEL genes. Clinical data of patients with streptococcal endocarditis were prospectively collected according to a pre-established protocol. Results: Patients with endocarditis represented 7/9 (77.8%) and 26/86 (30.2%) of the bacteraemias caused by S. tigurinus and other VGS, respectively (p < 0.001), in two of the hospital participants. Among patients with streptococcal endocarditis, 12 different Streptococcus species were recognized being S. oralis, S. tigurinus and S. mitis the three more common. No relevant statistical differences were observed in the clinical characteristics and outcomes of endocarditis caused by the different VGS species. Conclusions: In this multicenter study performed in Spain, S. tigurinus showed a higher predilection for the endocardial endothelium as compared to other VGS. However, clinical characteristics and outcomes of endocarditis caused by S. tigurinus did not significantly differ from endocarditis caused by other oral streptococci.JMM received a personal 80:20 research grant from the Institut d’InvestigacionsBiomèdiques August Pi i Sunyer (IDIBAPS), Barcelona, Spain during 2017–19.

Mendelian Randomisation Confirms the Role of Y-Chromosome Loss in Alzheimer’s Disease Aetiopathogenesis in Men

Mosaic loss of chromosome Y (mLOY) is a common ageing-related somatic event and has been previously associated with Alzheimer’s disease (AD). However, mLOY estimation from genotype microarray data only reflects the mLOY degree of subjects at the moment of DNA sampling. Therefore, mLOY phenotype associations with AD can be severely age-confounded in the context of genome-wide association studies. Here, we applied Mendelian randomisation to construct an age-independent mLOY polygenic risk score (mloy-PRS) using 114 autosomal variants. The mloy-PRS instrument was associated with an 80% increase in mLOY risk per standard deviation unit (p = 4.22 × 10−20) and was orthogonal with age. We found that a higher genetic risk for mLOY was associated with faster progression to AD in men with mild cognitive impairment (hazard ratio (HR) = 1.23, p = 0.01). Importantly, mloy-PRS had no effect on AD conversion or risk in the female group, suggesting that these associations are caused by the inherent loss of the Y chromosome. Additionally, the blood mLOY phenotype in men was associated with increased cerebrospinal fluid levels of total tau and phosphorylated tau181 in subjects with mild cognitive impairment and dementia. Our results strongly suggest that mLOY is involved in AD pathogenesis.P.G.-G. (Pablo García-González) is supported by CIBERNED employment plan CNV-304-PRF-866.

The aim of our study is to assess the relationship between fruit and vegetable (F&V) consumption and plasma FAs and their subtypes. Methods and Results: Plasma FAs are assessed in a cross-sectional analysis of a subsample of 240 subjects from the PREDIMED-Plus study. Participants are categorized into four groups of fruit, vegetable, and fat intake according to the food frequency questionnaire. Plasma FA analysis is performed using gas chromatography. Associations between FAs and F&V consumption are adjusted for age, sex, physical activity, bodymass index (BMI), total energy intake, and alcohol consumption. Plasma saturated FAs are lower in groups with high F&V consumption (-1.20 mg cL−1 [95% CI: [-2.22, - 0.18], p-value = 0.021), especially when fat intake is high (-1.74 mg cL−1 [95% CI: [-3.41, -0.06], p-value = 0.042). Total FAs and n-6 polyunsaturated FAs tend to be lower in high consumers of F&V only in the high-fat intake groups. Conclusions: F&V consumption is associated with lower plasma saturated FAs when fat intake is high. These findings suggest that F&V consumption may have different associations with plasma FAs depending on their subtype and on the extent of fat intake.Generalitat de Catalunya FI_B 00256Canadian Institutes of Health Research (CIHR)Consejo Interinstitucional de Ciencia y Tecnologia (CICYT)European Commission AGL2016-75329-RCIBEROBN from the Instituto de Salud Carlos III ISCIII from the Ministerio de Ciencia, Innovacion y Universidades, (AEI/FEDER, UE)Generalitat de Catalunya 2017SGR196CIBER Fisiopatologia de la Obesidad y Nutricion (CIBERobn)Instituto de Salud Carlos III (ISCIII), through the Fondo de Investigacion para la Salud (FIS)European Commission PI13/00673 PI13/00492 PI13/00272 PI13/01123 PI13/00462 PI13/00233 PI13/02184 PI13/00728 PI13/01090 PI13/01056 PI14/01722 PI14/00636 PI14/00618 PI14/00696 PI14/01206 PI14/01919 PI14/00853 PI14/01374Especial Action Project entitled Implementacion y evaluacion de una intervencion intensiva sobre la actividad fisica Cohorte PREDIMED-Plus grantEuropean Research Council (ERC) European Commission 340918Recercaixa grant 2013ACUP00194Junta de Andalucia PI0458/2013 PS0358/2016 PI0137/2018Generalitat Valenciana European Commission PROMETEO/2017/017SEMERGEN grant, Fundacio la Marato de TV3 PI044003Generalitat de Catalunya 2017 SGR 1717Ministerio de Ciencia, Innovacion y Universidades AGL2016-75329-R"FOLIUM" program within the FUTURMed project within Fundacio Institut d'Investigacio Sanitaria Illes BalearsICREA under the ICREA Academia programmeThe European Regional Development Fund PI17/01347 PI17/00525 PI17/01827 PI17/00532 PI17/00215 PI17/01441 PI17/00508 PI17/01732 PI17/00926 PI19/00781 CB06/03 CB12/03European Commission PI14/00972 PI14/00728 PI14/01471 PI16/00473 PI16/00662 PI16/01873 PI16/01094 PI16/00501 PI16/00533 PI16/00381 PI16/00366 PI16/01522 PI16/01120 PI17/00764 PI17/01183 PI17/00855 FPU17/00513 CD17/0012
